About I2C and CMOS cam

Hi everybody,

i'm working on a stratix, in order to interface a cmos cam ( C3088, Ov 6620) with the nios 2, and using the lancelot daughter board ( with the LCD controller) for displaying what i must get.

dispalying works ( 2D accelerator, images,...)

but the I2C make me in trouble these days, ( I need it to make the cam in order with her self and my design http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif )

I&#39;m using the I2C open core, and I ve pulled up the SDA and SCL, even in the design ( lvcmos, pull up on)

and I only can get FF.

So does any one help?

Thanks.

RBS
